Cron jobs or folder actions

Dear readers and professionals

Is it possible to have cron jobs and/or folder actions running with ATV?
I do a automatic FTP upload of TV shows recorded over oniletvrecorde.com.
I would like to do the following process.
1.) Decode the uploaded files
–> Can be done through a unix tool over bash scripting
2.) Move them according to their filenames
–> Stargate to folder “Stargate” and Stargate Atlantis to folder “Stargate Atlantis” and so on
3.) If the folder does not exist, then create it
4.) Update the file list of the movie player
–> This way I don’t have to update the list of films every time I start the player

Thank you for your help
Kind regards
Thomas Thaler
